backend/drm: fetch EDID manufacturer from udev_hwdb

Browse source 
Maintaining our internal table up-to-date is tedious: one needs to
manually go through the PnP ID registry [1] and check whether we're
missing any entry.

udev_hwdb already has an API to fetch a manufacturer name from its
PnP ID. Use that instead.
